SUMMARY OF THE INVENTION

The present invention relates generally to devices used to irradiateharmful bacteria and other “germs” within the human mouth and throat.The invented device, called a “light conductor” or “light conductordevice” utilizes light to treat infections and eliminate harmful germsand bacteria within the human body, with natural sunlight being theespecially-preferred light source and other sources of UV-spectrum lightbeing alternative sources.

The invented device may be used safely by an individual, withoutassistance, to treat infections by reducing or eliminating bacteria orother microorganisms that are susceptible to sunlight, specificallywithin the rear mouth and upper throat areas. The invented device may beused as a supplement to, or instead of, conventional and/or homeopathictreatments and medicines. The inventor believes that treatment at home,using the invented device, may help prevent or at least postpone theneed for doctor visits, emergency room visits, and antibiotics. Theinvented device may help those who are traveling or are far away frommedical care, for example, those who are hiking, sailing, or travelingor living in remote regions. Further, the inventor believes that someembodiments may be effective in treating, reducing or eliminating thebacteria in the mouth that cause many cases of “bad breath.”

The invented device is held in the mouth so that an elongated portion ofthe device extends at least to the rear of the mouth and preferably intothe upper region of the throat. The device is adapted to receive naturalsunlight at its outer, distal end and to carry it to its proximal endinside the user's throat. The distal end extending outside the mouth isplaced in the sunlight, and the sunlight travels through the device tothe proximal end inside the rear of the mouth or throat, from which thesunlight radiates. The proximal end is preferably designed to radiatelight in many directions at the same time, so that the natural sunlightreaches much of the surface of the rear mouth and upper throat. Byvirtue of sunlight's natural tendency to kill or otherwise inactivatemicro-organisms, the sunlight reduces or eliminates the micro-organismscausing the sore throat and illness.

The preferred embodiments are larger at the distal, sunlight-collectingend, thence tapering along the length of the device to the proximal,sunlight-emitting end. The preferred embodiments are preferablyconstructed of optically clear plastic and are also preferably at leastsomewhat flexible, permitting comfortable insertion within the mouth andat least some conforming to the interior contours of same. The opticallyclear plastic may be in the form, for example, of a single piece thatforms the entire or substantially the entire body of the lightconductor, or a bundle or group of light fibers extending along thelength of the body, as will be understood by one of skill in the fiberoptics.

Preferably, the preferred light conductor has no power source exceptthat it receives and transmits sunlight, for example, the preferredlight conductor has no battery and no electrical connection. Thepreferred sunlight conductor has no light-bulbs, no light-emittingdiodes, and no other devices that create or emit UV or other radiationexcept for structure and material from which sunlight may radiate.

The elongated light conductor structure is adapted to extend through theuser's mouth and to the upper throat area, preferably with minimal, orat least comfortable, contact with the tongue and the throat, by meansof the light conductor having a slightly curved shape and a size, shape,and thickness that fit well over the tongue and into the throat.Preferably, the light conductor is long enough to extend past all or asubstantial portion of the tongue, and is of proportions, shape, andflexibility or texture preferably do not trigger a gag reflex in mostpeople. The light conductor may be shorter than that shown in thedrawings for users that may comfortably place a device in their mouthbut feel they must keep it slightly forward of the throat. Also, thelight conductor may optionally be rigid or substantially rigid, but thismay tend to cause discomfort or gag reflex in more people.

The distal, light-collecting end need not be large or have a largesurface area, as the preferred optically-clear plastic, once hit bysunlight, will carry the light to the proximal end. The distal end maybe a small member, plate, or other protrusion that extends only 1-4inches from the mouth, for example. The optically-clear plastic of thedistal end is uncovered and unsheathed, so that all of it, or asubstantial portion of it, is exposed to light when the user stands inthe sunlight.

The middle portion of the tubular structure, between the distal andproximal ends, may be covered with a thin layer of opaque material,preventing sunlight captured at the distal end from exiting the deviceuntil said sunlight reaches and exits the proximal end of the tube.

The device may comprise some structure for helping the user position thelight conductor in his/her mouth, for example, a positioner forplacement at the outside of the lips and/or a positioner for beingbitten or clenched between the teeth. In the embodiments shown, a ringis placed around and affixed to the light conductor, in close proximityto the distal end, wherein said structure is comprised of soft, pliableand flexible material upon which the teeth are closed or clenched to aidin keeping the light conductor at the proper attitude within the mouthand allowing hands-free use of the device. This positioner structure,and the other portions of the light conductor, should be waterproof,easily cleaned, and resistant to available cleaning aids such as soapsand detergents.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the Figures, there are shown several, but not the only,embodiments of the invented light conductor device used to kill, weaken,or otherwise reduce the effects of harmful bacteria or other germs inthe throat. It is understood that the invented light conductor may alsoeliminate or reduce bacteria in the mouth or throat that are considered“good” bacteria or at least are considered not harmful. The preferredlight conductor provides mild enough treatment that the “good” bacteriaare not all destroyed as the harmful bacteria are reduced, and a morehealthy balance of “good” bacteria and “bad” bacteria is reestablished.

Referring now to FIG. 1, it may be observed that, in use, the lightconductor assembly 10 is inserted into the mouth M such that the distalend 14 of light conductor body 12 remains outside the lips so that itmay collect sunlight S. The proximal end 16 is located at the upperthroat area T. Sunlight S travels the length of conductor body 12 andexits through proximal end 16 to irradiate the interior of the throat.

While the light conductor assembly 10 is portrayed in FIGS. 1-8 as adevice that is fairly substantial in size relative to the mouth andthroat, but many embodiments will be much smaller in diameter, forexample, smaller in width and thickness all the way along the portion ofthe body adapted to be inside the mouth and throat. See, for example,FIGS. 15 and 16.

The teeth 30 of the person P are closed or clenched upon ring 20 to aidin keeping the light conductor 10 in the proper position within themouth M, thereby permitting the user to have his or her hands free forother tasks.

Referring now to FIG. 2, it will be seen that conductor body 12 islarger at the distal end 14 than at proximal end 16 and generally makesa more or less tapered transition in shape along its length from oval atthe distal end 14 to round at the proximal end 16. This shape allows fora requisite amount of sunlight to be collected at distal end 14 and tobe concentrated along the generally tapering length of light conductorbody 12 to provide the necessary amount of sunlight exiting conductorbody 12 at proximal end 16 to eliminate or reduce germs in the throat.FIG. 2 illustrates one, but not the only, shape with which lightconductor 10 may be constructed, for example, the light conductor 10 maybe generally square, triangular, round, or other shapes incross-section. Further, for embodiments that are used to reduce oreliminate “bad breath,” it may be beneficial to produce a lightconductor that is slightly shorter in length, and has a proximal endthat is flattened and relatively broad so that it emits light preferablyall the way across the width of the tongue and preferably over theentire or substantially the entire surface of the tongue.

Referring now to FIGS. 3, 7 and 8, it will be observed that conductorbody 12 is designed, in a side profile, with a generally-curved shape toaccommodate the curvature of the mouth and throat. Conductor body 12 iscomprised of optically-clear plastic as will be understood by those inthe fiber optics field after reading and viewing this application. Thegreater portion of conductor body 12, between distal end 14, at whichsunlight is collected, and proximal end 16, at which sunlight isdistributed into the throat, has disposed upon its outer surface cover18, comprised of an opaque, preferably resilient and pliable materialthrough which sunlight cannot penetrate. Cover 18 prevents sunlight fromradiating out of conductor body 12 until said light reaches proximal end16.

Referring now to FIGS. 3, 4 and 8, it may be seen that positioner ring20, comprised of, but not limited to, a relatively soft pliable materialsuch as rubber, is preferably adhesively attached to and surrounds body12 and cover 18. A user may gently clench the upper and lower frontteeth 30 upon positioner ring 20 (see FIG. 1), to aid in keeping thelight conductor 10 at the proper attitude within the mouth, and asaforementioned, allow hands-free use of the device.

Referring now to FIG. 5, it will be observed that the cross-sectionalshape of conductor body 12 may be constructed so as to permit of easierinsertion of the light tube 10 within the mouth. In this case, adepression 22 integrally molded within the lower portion of conductorbody 12 may aid in the insertion, and/or comfortable resting, of thedevice over the top of the user's tongue. Other shapes and contours,including a thinner, smaller-diameter conductor, may be provided; manyusers may feel that a very thin conductor, such as less than ½ inch fromtop to bottom surface and/or less than ½ inch in diameter, is easier totolerate in the mouth for the preferred several minutes of treatmenttime. See, for example, FIGS. 15 and 16. Also, the distal end and/orpositioner for being gripped between the teeth, for example, may besmaller, thinner, and/or other shapes and sizes as desired and aseffective for light conduction and/or comfortable use.

Referring now to FIGS. 5B and 6B, an alternate embodiment of theinvented device is shown wherein light transmitting light fibers 24,also constructed of optically clear plastic, are used to carry lightfrom distal end 14 of body 12 to proximal end 16. The light fibers 24may be received in a hollow casing that forms the conductor body, orotherwise contained inside the conductor body. The light transmittingtubes 24 fulfill all the functions of the solid or continuousoptically-clear plastic body of the first embodiment described in thepreceding narrative. Having a bundle of light fibers, which arethemselves somewhat flexible, inside a generally flexible casing, mayprovide more comfort for many users.

Referring now to FIGS. 9 through 13, illustrated therein is a thirdembodiment of the present invention wherein a conductor 10′ includes astorage battery power source 26 and light emitting diode source 16 areinstalled within body 12, wherein electrical connections 28 are providedto connect said power source with the light emitting diode or diodes 16.The diode(s) may be UV-LED's or other diodes that emit light of aspectrum that damages or kills the bacteria and micro-organisms that arethe target of the invention. Alternatively, other light sources may beused in embodiments of the invention, including various sources thatemit light in a spectrum or part of a spectrum that are effective indamaging, reducing, and/or killing the bacteria or other micro-organismsthat are the target of the invention. Also, as an alternative to theembodiments shown in the drawings, the invention may include embodimentsusing a “passive” light conductor such as that shown in FIGS. 1-8 (whichtypically relies on gathering of natural sunlight rather than light froma man-made source) combined with a separate but easily-attachable andeasily-detachable “active” light source. Examples of such a light sourcemight be a battery-powered or electrical-grid-powered light source thatclips-on or is otherwise attachable to and removable from the passivelight conductor, for example, attachable to the distal end so that itneed not reach into the mouth of the user.

Alternatively, the battery and LED(s) may be combined together in a unitgenerally in the central portion of the body of the device, and fiberoptic tubes or a larger member of optically-clear plastic may beinterposed between the battery/LED unit and the light-emitting proximalend. Such light fibers, or other optically-clear member(s) wouldtransmit light generated by the battery and LED unit to the proximalend, which end would preferably be an unsheathed, optically-clearplastic member adapted to radiate light out to the mouth and throat.

In these battery-powered embodiments, the general shape and principle ofoperation may remain the same as in the preferred embodiments, however,the light conductor body may be comprised of an opaque material, withthe exception of proximal end 16, as there is no sunlight being gatheredat the distal end 14′ for transmission through the body of theconductor. Light in these battery-powered embodiments is beingtransmitted from an LED in the proximal end or inside the body, so lightonly needs to travel from the LED out of the proximal end to the mouthand throat. If the LED is provided at the distal end, the light willonly have to travel through the LED cover/casing. If light travels froman LED(s) located away from the end of the conductor body, light fibersor a larger light-transmitting member may be provided to carry thelight, and the body itself will not necessarily need to beoptically-clear.

The distal end 14′ of such embodiments, not being used to collectsunlight, may be of a different shape, for example, a flared or slightlyenlarged end, preferably sufficient only to prevent swallowing orchoking on the device by the user.

FIGS. 15 and 16 illustrate an especially-preferred substantially-taperedlight conductor 10″ according to another embodiment of the invention,which better illustrates how the dimensions may be reduced to be quitesmall, in order to be more comfortable and less intimidating to manyusers. The size of the preferred embodiments, especially the portionextending to the throat, may be reduced to be quite thin both in theside-to-side dimension and in the top-to-bottom dimension, as long asthe light still travels efficiently from the distal end to the proximalend, as will be understood after viewing this disclosure by those in thefield of fiber optics.

The main body of the light conductor may have alternative shapes andcontours, and also the distal end and proximal end may have alternativeshapes and contours. For example, while the proximal end shown in FIGS.7 and 13 may be called generally semi-spherical or a portion of asphere, other shapes may be used with a goal of emitting/radiating lightin many directions from the proximal end. For example,emitting/radiating at least 180 degrees around the proximal end, and,more preferably, 180-340 degrees around the proximal end. An oval,elongated, cylindrical, or other proximal end shape may be used toprovide surface area that does not focus the light in one direction butsubstantially all around the rear mouth and/or the upper throat.

In summary, many light conductors according to embodiments of theinvention may be described as: A light conductor device for treatingsore throat and other ailments caused by bacteria or othermicro-organisms in the throat, the light conductor having an elongatedbody having a proximal end adapted for insertion into the human mouthand a distal end adapted for being outside the mouth and receivingnatural sunlight, the elongated body comprising optically-clear plasticextending between the distal end and the proximal end so that saidnatural sunlight received by the distal end is transmitted to saidproximal end from which it radiates out from the light conductor intothe throat of the user to radiate said bacteria or othermicro-organisms. The light conductor device may have no power sourceother than the sunlight being received on said distal end, and,preferably, the conductor device has no battery and no connection to anyelectrical power source.

The light conductor device may have an elongated body made substantiallyof optically-clear plastic, or an elongated body comprising light fiberswhich are said optically-clear plastic, both the plastic body or thebody holding light fibers being adapted to carry said natural sunlightfrom said distal end to said proximal end. Said proximal end preferablyis adapted to radiate sunlight in greater than 180 degrees around theproximal end, for example, by means of being shaped generally as apart-spherical or semi-spherical surface, or a generally cylindricalsurface, adapted to radiate sunlight to the throat. Most preferably, theproximal end is adapted to radiate sunlight almost 360 degrees(typically about 340 degrees, leaving room for the body of the deviceconnecting to the proximal end) around the proximal end so that thesunlight reaches substantially the entire upper throat.

The device may be made in different sizes and lengths for children,teens, and adults, for example, ranging from about 4 to 12 inches long,and more typically, from about 5 to 8 inches long. The device may becurved on a radius between said proximal end and said distal end, sothat the proximal end may curve down into the throat. Many of theembodiments will be curved on about a 4-6 inch radius.

The light conductor distal end typically only needs to protrude from themouth (beyond the lips) about 1-4 inches, as sunlight will hit thedistal end and, due to the natural properties of sunlight and thepreferred materials of the device, will travel efficiently through thedevice to the proximal end. The user may want to tilt his/her head backslightly to allow the sun to hit a substantial portion of the distalend, as shown in FIG. 1. Alternatively, a larger plate or sun-collectingmember may be integral with or attached to the distal end.

The user may find the invented device an easy-to-use self-treatmenttool, and may find that even a few minutes of self-treatment will help.Use of the device does not require a doctor or nurse or other assistant,but users are encouraged to monitor their health and seek medical adviceif the sore throat persists more than a few days. Typically, theinventor recommends 2-15 minutes of use per treatment, and morepreferably, 3-5 minutes of use per treatment, with multiple treatmentsseparated by ½-4 hours. The user should be careful not to overuse thedevice, due to possible concerns about over-exposure to sunlight. Theinvented device is not intended for sterilization during root canals, orother dental work, and the invented device preferably does not includeany tooth brushing member.

In the embodiments including a battery and one or more LED's, featuressimilar to those of the sunlight-powered device may be included, forexample, the part-spherical, semi-spherical, cylindrical, orsemi-cylindrical proximal end, the curvature and/or contours and/orpreferred (but not required) flexibility for making the device morecomfortable in the mouth. One would expect that battery-poweredembodiments would also be in the range of 4-12 (more preferably 5-8)inches long and curved on a 4-6 inch radius. The distal end of suchembodiments could be smaller/shorter as it need not collect sunlight;for example, such distal ends may protrude about 0.5-2 (more preferably−0.5-1 inch) from the mouth.

Embodiments of the invention may include methods of using a lightconductor to help cure sore throats or other illness. The methods mayinclude not connecting the device to any external power source (exceptthe sun). The preferred methods may include not treating the teeth, rootcanals, or sinuses, but, preferably, treating the throat.
